I have a boresnake I use for my .270 WSM, and one for my buckmark .22lr pistol. I am wondering what the proper technique is for using the bore snake. I have just been running it through the barrell a couple of times and it appears to be doing a very good job of cleaning them. Should I be putting any type of slovent on it before I run it through the barrel? What are the odds of it breaking while in the barrell? I have to exert a large amount of force to pull it through the barrel. Especially the .22.

I just want to make sure I am using it most efficiently.

thanks
